The Voice banks on Holly Willoughby and her boobs

TV bosses want her to flash more cleavage to reel in viewers in time for the series finale of three live shows.

Saturday’s audience of 5.9million is the lowest so far this year for the BBC talent contest.

But it seems it is not the acts causing viewers to switch off. It is apparently because Holly’s famous cleavage has been covered up.

Two weeks ago, when the 32-year-old presenter wore a very revealing top, the show pulled in 7.5m viewers.

In a later show, Holly covered up and ratings fell to 7.1m. On Saturday’s double episode, the blonde presenter started off in a very low cut black outfit. But midway she changed into a modest round necked top. As a result, ratings fell to 5.9m.

Now Beeb chiefs have called on the sexy host and her stylists to help save their show.

TV bosses want her to flash more cleavage to reel in viewers in time for the series finale of three live shows.

And it seems cheeky Holly is keen to oblige.

She said at The Voice launch party back in March: “I am guaranteed to be naked for the three shows.”
